What is a lopsided smile?

 A lopsided smile is an uneven smile. It appears uneven in a way where the left side and the right side of the mouth do not match. One side of the face is pulled up in a way where it’s smiling and the other side is the opposite which means it may be downturned.

What causes a lopsided smile?

Below are some health conditions that can cause an asymmetrical face:


Sometimes genes and development can cause a lopsided smile. If it runs in your family, chances are that you might have it too.

Lifestyle habits

Sometimes having a poor posture, or sleeping with your face pressed against the pillow, and some other similar habits can all contribute to having an asymmetrical face.


Injury to your face in childhood, having facial surgery due to an injury, or experiencing trauma can sometimes cause a lopsided smile.

Bell’s Palsy

Bell’s Palsy is caused due to paralysis of facial nerves. It weakens the muscles on one side of your face and can cause a lopsided smile.  

Sun Damage

With growing age, exposure to the sun and it’s UV rays may lead to developing spots, patches, and moles on your skin. This can be caused to one side or area of your face, where there is the maximum amount of sun damage.


Smoking regularly exposes you to toxins, hence increasing the chances of having an asymmetrical face. 

Dental Work

The use of dentures or having dental veneers may sometimes change the symmetry of your face. Getting a tooth extracted, causes changes in the facial muscles which may be another cause for asymmetry.


The facial asymmetry increases with your growing age. Naturally, your ears and nose grow as you change, causing asymmetry.


There are different signs of a stroke, when you identify signs such as dropping of the face or your smile is suddenly uneven you must immediately consult a doctor. 

Experiencing numbness and difficulty in speaking are also some common signs of a stroke.


Also known as a twisted neck, is a condition where the person has abnormal positioning of neck muscles. This condition can sometimes take place in the womb itself.

Most cases are temporary and the symptoms can be resolved, it is hardly ever permanent.

Various other health conditions can cause a lopsided smile or contribute to facial asymmetry. Apart from health conditions, sometimes there are other reasons why people may intentionally use a lopsided smile.

What are some uses of a lopsided smile?

  • Smirking or trying to flirt
  • Joking around or making a sarcastic comment
  • To portray humour and uncertainty

When people don’t want to be perceived seriously in certain situations, they often use a lopsided smile.
